In Carcassonne: The Plague, first released in both the German and English editions of issue 2010/6 of Spielbox magazine, pestilence descends upon Carcassonne, spreading under the players' control across the landscape tiles and carrying off any followers unfortunate enough to be located there.

Carcassonne: Corn Circles, Plague & Tunnels had been announced as a release by Rio Grande Games for 2012. It would contain three small expansions each previously published on their own: Crop Circles, The Plague, and Tunnels. It has since been cancelled.
